Notes Wall Mounted Terminations: REAR VENT
All dimension lengths for vertical or horizontal runs are
„
measured from center of the vent pipe.
Venting runs must fall within the limits set by the venting
„
graphs, see Figure 14 or 14a.
Fireplace must be converted to Rear Vent configuration
„
prior to running vent, see Figure 8 and 8a.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre
of the termination and the horizontal run from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting
Graph Figure 14 or 14a with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 114" and the
horizontal run to the wall flange of the vent termination is
126", this would be an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 66" and the horizontal
run to the wall flange of the vent termination is 84", this would
NOT be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 72"
and the horizontal run to the wall flange of the vent termination
is 144", this would NOT be an acceptable installation.
